THE FOCUS RIGHT NOW

BUILD THE ENGINE.

Twelve weeks out, you're still building the base — but specific structure is starting to appear. Tempo work enters the picture one day a week. Long rides get longer. This is where the event-specific fitness starts to take shape without compromising your aerobic foundation.

THIS WEEK'S ANCHOR SESSION

TEMPO SANDWICH

2x20min at tempo (76-88% FTP) inside a 2-hour Z2 ride. Steady, controlled, not a time trial. This is your first taste of extended race-pace efforts.

EVENT INTEL

WHAT THE GRAN FONDO NYC ACTUALLY DEMANDS

Gran Fondo New York (GFNY) is the flagship USA sportive — 160km from the George Washington Bridge up the Hudson Valley with 2,500m of climbing. Competitive timed format (your position matters), international field, closed bridge at the start.

KEY CHARACTERISTICS

✓Start on the George Washington Bridge — 8,000+ riders
✓Bear Mountain climb — the signature climb at km 90
✓Timed format: results matter, pacing strategies ruthless
✓Rolling Hudson Valley terrain — few flat km
✓May weather: anywhere from 10°C and raining to 30°C and humid

COMMON MISTAKES

✕Burning matches matching pace on the first 30km — it's a race start, not your pace
✕Riding solo instead of working groups — drafting saves 25-30% on the Hudson roads
✕Underfueling because the early rollers feel 'just easy enough'

PACING

Get in a pack at your sportive pace within the first 15km. Work the pack on the flats + rollers. Bear Mountain at km 90 is a 25-30 min threshold effort — attack it at 90-95% FTP if you're chasing a time, 80-85% if you're chasing a finish. The back half rewards steady pacing over heroic climbs.

FUELLING

80-90g carbs/hour. Feed zones at km 55 and km 110 are strategic. Don't skip the km 55 stop. US roadie fuelling culture means everyone carries their own — don't rely on aid station variety.

KIT

Aero road bike with 11-30 cassette. Arm warmers + gilet stashed — weather varies. Rear light mandatory (enforced). Sunglasses with clear lenses for the GW Bridge tunnel at the start.

FAQ

COMMON QUESTIONS AT 12 WEEKS OUT

Is 12 weeks enough to train for the Gran Fondo New York?+

Yes, 12 weeks is a strong window. That's enough time for a full base phase, build, peak, and taper — the classical periodisation structure. 2,500m of climbing over 160km is built with sustained Z2 volume (base) + threshold work (build) in that order.

What's the hardest part of the Gran Fondo New York?+

Start on the George Washington Bridge — 8,000+ riders. burning matches matching pace on the first 30km — it's a race start, not your pace — so pacing discipline is the single biggest lever most amateurs miss. Get in a pack at your sportive pace within the first 15km.

How many hours a week should I train at 12 weeks out from the Gran Fondo New York?+

Aim for 8-12 hours/week if you're targeting a strong finish. The long weekend ride is the anchor (3-4 hours at build intensities) plus 3-4 structured weekday sessions. Volume matters more than intensity at this phase.

Do I need a coach to train for the Gran Fondo New York?+

You don't need a coach to finish. You do need structure. If you're new to sportives, have a target finish time, have a plateau you can't break, or have a history of peaking wrong, a coached plan pays for itself. Inside Not Done Yet the plan is built backwards from your event date — base, build, peak, taper timed to the week the Gran Fondo New York runs. 7-day free trial, $195/mo.

What gearing should I run for the Gran Fondo New York?+

Aero road bike with 11-30 cassette. Arm warmers + gilet stashed — weather varies. Rear light mandatory (enforced). Sunglasses with clear lenses for the GW Bridge tunnel at the start.
